Effective Field Theory of Operator Scrambling from Strong-to-Weak Symmetry Breaking
Bai-Lin Cheng, Shao-Kai Jian, Zhi-Cheng Yang
Operator scrambling is commonly diagnosed by the growth of out-of-time-ordered correlators (OTOCs), yet a general symmetry principle underlying their effective dynamics has remaine…

Uncovering Quantum Many-body Scars with Quantum Machine Learning
Jiajin Feng, Bingzhi Zhang, Zhi-Cheng Yang +1
Quantum many-body scars are rare eigenstates hidden within the chaotic spectra of many-body systems, representing a weak violation of the eigenstate thermalization hypothesis (ETH)…
